Rhizoctonia solani causes okra (Abelmoschus esculentus) seedling damping-off in South China with biological characterization and fungicide sensitivity profiling

mycolabadmin

Researchers identified Rhizoctonia solani as the fungus causing a serious disease in okra seedlings in southern China that was destroying about 35% of crops. The fungus dies when exposed to high temperatures (45-48°C) and grows best at about 28°C. Among seven tested antifungal treatments, a combination of trifloxystrobin and tebuconazole was most effective at controlling the pathogen, providing farmers with practical strategies for managing this crop disease.

Two new Cordyceps-like species, Perennicordyceps zongqii sp. nov. (Polycephalomycetaceae) and Purpureocillium zongqii sp. nov. (Ophiocordycipitaceae), in Hypocreales from karst region of China

mycolabadmin

Scientists discovered two new types of specialized fungi in the karst regions of China that infect insects and live in soil. These fungi, named Perennicordyceps zongqii and Purpureocillium zongqii, were identified using genetic analysis and microscopic examination. The findings highlight how special cave and valley environments in karst regions support unique fungal species that haven’t been previously documented in these areas.

Descriptions of 19 Unrecorded Species Belonging to Sordariomycetes in Korea

mycolabadmin

Scientists in Korea discovered and documented 19 species of fungi that were previously unrecorded in the country. These fungi were found in soil and freshwater environments across Korea. Using microscopy and DNA analysis, the researchers confirmed the identity of each species and provided detailed descriptions and illustrations. This discovery helps us better understand the fungal diversity present in Korean ecosystems.

Overview of hirsutella-like anamorphs in Ophiocordyceps (Sordariomycetes, Ophiocordycipitaceae): introducing two new species and one new record from China

mycolabadmin

Scientists discovered and described two new species of parasitic fungi that infect insect larvae in China. These fungi, belonging to the Ophiocordyceps genus, have special asexual reproductive structures called hirsutella-like anamorphs. The research provides a comprehensive catalog of all known Ophiocordyceps species with these structures and how they differ from each other based on their shape and size.

Two Novel Exophiala Species Isolated from Galls on the Chinese Magnolia-Vine (Schisandra Chinensis) in Korea

mycolabadmin

Scientists in Korea discovered two previously unknown types of black yeast fungi living inside galls (abnormal growths) on Chinese magnolia vines caused by tiny gall midge insects. Using genetic testing and microscopic examination, they identified these as entirely new species of fungi. These fungi appear to have beneficial relationships with their host plants, potentially helping them grow better and resist environmental stress. This discovery adds to our understanding of the diverse fungal species in Korea and their interactions with plants and insects.

Clonostachys rosea, a Pathogen of Brown Rot in Gastrodia elata in China

mycolabadmin

Researchers in China identified a fungus called Clonostachys rosea as the cause of brown rot disease affecting Gastrodia elata (Tian Ma), an important medicinal orchid plant. The disease causes brown spots on tubers that expand and darken, significantly reducing crop yield and quality. The study involved detailed examination of the fungus under microscopes, genetic analysis, and confirmation that the fungus could cause disease in healthy plants. These findings will help farmers prevent and control this disease through proper soil management and selection of healthy seed tubers.

Morpho-phylogenetic evidence reveals novel Bambusicolous fungi from Guizhou Province, China

mycolabadmin

Researchers in Guizhou, China collected and studied fungi living on dead bamboo stems. They identified five fungal species belonging to the Bambusicolaceae family, including three completely new species previously unknown to science. By examining the fungi under microscopes and analyzing their DNA, scientists confirmed these new species and found that one previously known species had a new form never before documented. These findings help us better understand the diverse fungal communities that play important roles in breaking down bamboo and recycling nutrients in forest ecosystems.

Identification and biological characteristics of Fusarium tobaccum sp. nov., a novel species causing tobacco root rot in Jilin Province, China

mycolabadmin

Scientists in China discovered a new type of fungus called Fusarium tobaccum that causes a serious disease in tobacco plants called root rot and wilt. By analyzing the fungus’s genetic material and physical characteristics, they confirmed it was a previously unknown species. The researchers also studied how this fungus grows under different conditions like temperature and soil pH to better understand how it causes disease.

Morphological and Phylogenetic Characterization of Raffaelea xyleboricola sp. nov. from Xyleborus Beetles in Korea

mycolabadmin

Researchers discovered a new fungal species living inside ambrosia beetles collected from Korean apple orchards. By examining the fungus under a microscope and analyzing its genetic material, they confirmed it was previously unknown to science. This fungus, named Raffaelea xyleboricola, may help scientists better manage beetle-related tree diseases and protect apple orchards.

Verticillium-like Anamorphic Fungi in Sordariomycetes from Southwestern China: Two New Taxa and a New Record

mycolabadmin

Researchers discovered two new fungal species in southwestern China’s rainforests: Leptobacillium gasaense and Ovicillium yunnanense. They also documented the asexual reproductive structures of Muscodor coffeanus, an endophytic fungus known for producing antibiotic compounds. These findings expand our understanding of beneficial fungi that can control pests and diseases in agriculture and forestry.
